I built an app that competes with Notion and Obsidian
App summary: Local-first productivity tool that combines note-taking, task tracking and journaling into one simple app. Advantages over Notion: Way simpler UI, all user data is only stored locally on their device - providing significantly faster load time, fully functional offline mode and complete privacy of their data Advantages over Obsidian: Dedicated features for task tracking and journaling - not just note-taking, with cheaper end-to-end encrypted device syncing compared to Obsidian Sync
